\ JOHN ALBERT FISH, OF sr. JOHN, NEW BRUNSWICK, CANADA.

WATER-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 351,859, dated November 2, 1886.

Application filed February 20, 1886. Serial No. 192,669. (I\o model.)

Be it known that I, JOHN ALBERT FIsH, of St. John, Province of New Brunswick, Canada, have invented certain new and useful I mprovements in WVaterHeating Apparatus, of which the following isa specification.

This invention has for its'object to provide a simple and efficient apparatus for heating -and circulating water for warming purposes; and it consists in the several improvements hereinafter described and claimed.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of the exterior of my improved apparatus. Fig. 2 represents a side elevation of the same. Fig. 3 represents a section on linear :r, Fig. 1. Fig. 4 represents a'section on line yy, Fig. 3. Fig. 5 represents a section on line z 2, Fig. 2. Fig. 6 representsaview of one of the sections of the diaphragm hereinafter described.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the inclosingcasing of the brick-work, said casing containinga fire-box, b, grate c, and the bridgewall e at the back of the lire-box. The bridge-wall is built with a ledge, e, at its front side, a little above the grate, and on said ledge rests a receiving pipe or header, f, extending across the fire-box and through the side walls of the easing, as shown in Figs. 4. and 5. With said rec'eivingheader communicate the lower sections or lengths of two series of pipes, g 9, ex-

tending from the header f along the sides of the fire-box, and along the sides of the casing above the fire-box, and back and forth above the bridge-wall, to a pipe, h,'whioh I term the flow-header, extending across the upper part of the casing, the ends of said header being let into the side walls'of the. casing.

A series of vertical pipes, 1', rise from the,

fire box, and to the products of combustion in the casing above the fire-box, so that it enters the flow-header h in a heated condition.

From the flow-header extend distributing I pipes m, which convey the heated water to the rooms to be warmed. The cooled water is returned to the receiving-header by returnpipes 11., entering return-headers 0 0, connected by elbows p p with the ends of the receivingheader. The water is continuously circulated,

risingfrom the receiving-header through the at the rear side of the diaphragm to the flue in the lower portion of the casing communicating withthe chimney, as shown by the arrows in Fig. 3. All parts ofthe pipes gj are thus subjected to the action of the heat.

The diaphragm p is composed of plates or sections 2, (one of which is shown detached in Fig. 6,) each recessed to receive a row of the pipes gj. Said plates have ears 3 at their-ends, through which pass vertical rods 4, held by lugs 5, affixed to the walls of the casing.

The pipes g and j are preferably made of wrought-iron, and the return-bends that connect said pipes are preferably of cast-iron,with right and left hand screw-threads.

It will be seen that the location of the receiving-header f at the front of the bridge-wall and near the grate, the arrangement of the lower sections of the pipes g g at the sides of the fire-box, and the arrangement of the vertical pipesi atthe rear and of the lower sec- ;tions of the pipes j over the fire-box insure the rapid heating of the water entering the receiving-header, said pipes beingexposed to the best possible advantage to the direct action of the fire. The extension of the pipes g j through the casing above. the fire-box and bridge-wall, together with the diaphragm p, insures the utilization of the heated products ICO of combustion passing from the fire-box. The diaphragm also supports the pipes and prevents them from sagging. Cocks it in the elbows p 1) enable the water to be drawn off from the entire system of pipes.

I claim 1. In a water-heating apparatus, the casing having the fire-box, grate, and bridge-Wall, combined with the receiving-header extending across the casing at the front side of the bridgewall and above the grate, the pipesgg, extending from said receiving-header along the sides of the fire-box and through the easing above the bridge-wall, the series of pipes 2', extending upwardly from the receivingpipe at the rear end of the fire-box, the series of pipes j, communicating with the vertical pipes, and extending over the firebox and through the casing above the bridge-wall, the flowheader located in the upper partof the casing and communicating with the pipes gj, distributing-pipes extending from the flow-head, er, and return-pipes n and return-headers 0, to return the water to the receiving pipe, as set forth.

2. In a water heating apparatus, the casing having the fire-box, grate, and bridge-wall,

combined with the receiving-header extending across the casing at the front side of the bridge-wall and above the grate, the pipes g 9, extending from said receiving-header along the sides of the fire-box and through the easing above the bridge-wall, the series of pipes 1', extending upwardly from the receiving-pipe at the rear end of the fire-box, the series of 5 pipes j, communicating with the vertical pipes, and extending over the fire-box and through the casing above the bridge-Wall,the flow-heador located in the upper part of the casing and communicating withthe pipes g j, the diaphragm extending upwardly from the bridgewall around the return-pipes, distributingpipes extending from the flow-header, and returnrpipes a and return-headers 0, to return the water to the receiving-pipe, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 16th day of January, 1886.

JOHN ALBERT FISH.
